HI-LOW UNLOADING BLOCKS FOR TANDEM PUMPS

Many systems require a high volume at low pressure for rapid traverse of a vise or tool, and then low volume, high pressure for clamping or feeding. This can
be accomplished by a hi-low circuit using two pumps. During rapid traverse,
both pumps supply the system. When pressure rises during clamping or feed, the large-volume main pump unloads, and the small pump maintains pressure. Output flow of the small pump is low enough to prevent heating of the oil.
